Malossi Contra Spring for Aprilia / Piaggio 50cc 2T

VARIABLE-SPEED DRIVE ADJUSTER SPRING

82% stiffer than the original.

The stiffer the contra string, the more resistance it has against the progression of the belt on the variator. The CVT transmission is a delicate balance, but when tuned correctly the red spring allows the engine to rev higher through the progression of the belt position on the variator, this keeps the RPM to maximum through the gear change.
